Description

  The present invention relates to a construction machine to which a traveling device can be attached and detached, and a method of attaching the traveling device to the construction machine.

  Large construction machines are dismantled and transported to the site and assembled locally. When the traveling device (crawler side frame) is attached to the construction machine body when assembled locally, the traveling device is lifted by a crane and attached and fixed to the construction machine body. At this time, pins are fixed at at least two places so that the traveling device does not rotate. In general, pin hole fixing parts are respectively formed on the construction machine side and the traveling device side, and pins are inserted and fixed in a state in which the pin holes formed in each are accurately matched. .

  However, it is very difficult to make the pin holes coincide with each other with high accuracy in a state where the traveling device is lifted by a crane, and it takes a long time, resulting in poor attachment workability. Therefore, there is also a construction machine in which one portion (the upper fixing portion) of the fixing portion is formed into a guide hook shape instead of the pin hole fixing in order to improve the mounting workability.

Japanese Patent Application Publication No. 06-016388

  However, if one portion of the fixing portion is in the form of a guide hook, a large load acts on the pin engaged with the guide hook, so the size (diameter) must be made larger than the pin used for the pin hole fixing portion There is a problem that a large space is required structurally. Such a structure can not be adopted particularly when there is a dimensional restriction due to the restriction of the transport width or the like.

  Therefore, the present invention has been made to solve the above-described problems, and a construction machine and a traveling device capable of efficiently attaching a traveling device to a construction machine main body by pin fixing without enlarging the attachment structure. The purpose is to provide a mounting method.

One embodiment of the present invention made to solve the above problems is a construction machine to which a traveling device can be attached and removed, provided on the construction machine main body side, and a construction machine side bracket provided with a plurality of fixing pin holes; A traveling device side bracket provided on a traveling device side and having a pin hole for fixing corresponding to a pin hole of the construction machine side bracket, and formed on either the construction machine side bracket or the traveling device side bracket And a guide pin which aligns the pin hole of the traveling device side bracket with the pin hole of the construction machine side bracket by the engagement of the guide hook, and the guide pin together provided rotatably to a bracket guide hook is not formed, by turning in a state in which the guide hook is engaged, the guide hook And wherein the moving the position of the pin holes in the bracket are formed in the vertical direction.

In this construction machine, when mounting the driving device to the construction machine body, by matching the pin hole of the traveling device side bracket and the pin hole of the construction machine Gawabu racket, a pin hole by driving a fixing pin, a driving device Attach to the construction machine body. Specifically, first, by moving the traveling apparatus lifting a crane, not a guide hook formed on one of construction machine side bracket or run line device-side bracket, and plan the hook is formed Engage with guide pins provided on the bracket. Thereby, alignment of the pin hole formed in each bracket is performed. Next, adjust the height position by vertically moving the position of the pin hole of the bracket in which the guide hook is formed by rotating the guide pin while the guide hook is engaged with the guide pin Do. Thereby, the centers of the pin holes formed in the respective brackets can be accurately aligned. Then, the fixing pin is driven into the pin hole whose center is aligned. Thereafter, the fixing pin is also driven into the other pin holes, and the traveling device is attached and fixed to the construction machine body. That is, the traveling device is pin-fixed at a plurality of places with respect to the construction machine main body. Therefore, since a large load does not act on the guide pin, it is not necessary to increase the size (diameter) of the guide pin.

  As described above, according to this construction machine, the centers of the pin holes formed on the brackets and into which the fixing pins are initially driven can be precisely aligned with each other by a very simple operation of rotating the guide pins. The fixing pin can be driven in efficiently. Thus, the mounting of the traveling device to the construction machine can be efficiently performed by pin fixing. And it is not necessary to enlarge the size (diameter) of the guide pin. Therefore, the traveling device can be efficiently attached to the construction machine body by pin fixing without increasing the size of the attachment structure.

  In addition, since the guide hook is engaged with the guide pin during the mounting operation of the traveling device, the traveling device lifted by the crane is supported by the guide pin and the guide hook. As a result, the traveling device lifted by the crane does not move carelessly, thereby improving the safety during work.

  Further, in the construction machine described above, in the guide pin, an engagement portion engaged with the guide hook is at a position where the pin outer peripheral surface formed by the outer circumference circle of the guide pin and the center of the guide pin are eccentric. It is preferable that the eccentric outer peripheral surface is formed by a circumference which is centered and which has a diameter different from the diameter of the guide pin and which is formed by a circumference partially overlapping the outer periphery of the guide pin.

  By forming the guide pin in such a shape, the height position can be adjusted by moving the position of the pin hole of the traveling device side bracket in the vertical direction by the eccentric outer peripheral surface with a very simple configuration. Thereby, the centers of the pin holes formed in the respective brackets can be accurately aligned.

  Then, after the fixing pin is driven in, it can be separated from the guide hook by rotating the guide pin again. Thus, no load acts on the guide pin. Here, during the mounting operation of the traveling device, that is, while the guide hook is engaged with the guide pin, a load acts on the guide pin, but since the traveling device is lifted by the crane, a very large load acts do not do. Therefore, it is not necessary to make the size (diameter) of the guide pin engaged by the guide hook larger than that of the fixing pin, and a structurally large space is not required.

Furthermore, in the construction machine described above, the guide pin is provided on the construction machine side bracket, and the plurality of pin holes provided on the construction machine side bracket and the guide pin are arranged in a straight line in the vertical direction. Is preferred.

  By doing so, since the construction machine side bracket can be miniaturized in the width direction, the width dimension of the construction machine main body can be reduced. Thereby, the present invention can be applied to a large-sized construction machine having a limited transport width.

Another embodiment of the present invention made to solve the above problems is a method of attaching a traveling device to a construction machine main body locally, in a mounting method of a traveling device, a lifting process of lifting the traveling device with a crane, and construction provided on the construction machine main body It has a cam mechanism in which a guide hook formed on either the machine side bracket or the traveling device side bracket provided on the traveling device which is lifted by a crane is rotatably provided on the bracket on which the guide hook is not formed. An engaging step of engaging with a guide pin, and a pin of a bracket in which the guide hook is formed by the cam mechanism by rotating the guide pin in a state in which the guide hook is engaged with the guide pin The position of the hole is moved vertically, and the center of the pin hole of the traveling device side bracket and the pin hole of the construction machine side bracket Characterized in that it comprises: an aligning step of aligning with the heart; and a fixing step of driving the fixing pin into the aligned pin hole and fixing the traveling device to the construction machine by the fixing pin at a plurality of locations. Do.

In the mounting method of the traveling device, in the engaging step, the guide hook provided on either the construction machine side bracket or the traveling device side bracket is rotatably provided on the bracket where the guiding hook is not formed. Engage with a guide pin having a cam mechanism. Then, in the alignment step, with the guide hook engaged with the guide pin, the guide pin is rotated and the position of the pin hole of the bracket in which the guide hook is formed is vertically moved by the cam mechanism. Align the center of the pin hole of the traveling device side bracket with the center of the pin hole of the construction machine side bracket. Thus, the centers of the pin holes formed on the respective brackets and into which the fixing pins are initially driven can be made to coincide with a very simple operation of rotating the guide pins. Therefore, the fixing pin can be driven in efficiently in the fixing step. Thus, the mounting of the traveling device to the construction machine can be efficiently performed by pin fixing.

  Further, in the fixing step, the traveling device is pin-fixed at a plurality of places with respect to the construction machine body. Therefore, since a large load does not act on the guide pin, it is not necessary to increase the size (diameter) of the guide pin. Therefore, the traveling device can be efficiently attached to the construction machine body by pin fixing in a limited space.

  In the mounting method of the traveling device described above, it is preferable that the method further includes a separation step of rotating the guide pin to separate it from the guide hook after performing the fixing step.

  By including such a separation step, it is possible to prevent the load from acting on the guide pin after the traveling device is attached to the construction machine body. Here, during the mounting operation of the traveling device, that is, while the guide hook is engaged with the guide pin, a load acts on the guide pin, but since the traveling device is lifted by the crane, a very large load acts do not do. Therefore, it is not necessary to make the size (diameter) of the guide pin engaged with the guide hook larger than that of the fixing pin, and a large space is not necessary for providing the guide pin.

  According to the mounting method of the construction machine and traveling device according to the present invention, the traveling device can be efficiently attached to the construction machine main body by pin fixing without enlarging the mounting structure.

  Hereinafter, an embodiment of a construction machine and a method of attaching a traveling device according to the present invention will be described in detail based on the drawings. In this embodiment, a tubing device to which a crawler side frame (traveling device) can be attached and detached is described. Thus, the tubing device will be described with reference to FIGS. 1 to 3. FIG. 1 is a plan view of the tubing device of the present embodiment. FIG. 2 is a side view of the tubing device of the present embodiment. FIG. 3 is a front view of the tubing device of the present embodiment.

  The tubing device 1 is a construction machine that performs press-in and pull-out on the ground while rotating a casing (or a steel pipe pile or the like) gripped by a chuck mechanism. The crawler side frame 30 can be attached to and detached from the tubing device 1. When transporting, the crawler side frame 30 may be removed at the time of transportation, and the crawler side frame 30 may be attached locally to travel by itself. 1 to 3 show the tubing device 1 in a state in which the crawler side frame 30 and the weight rack 50 are attached.

  In the configuration of the tubing device 1, elevating cylinders 4 are provided at four corners of a rectangular base frame 3, and elevating frames 2 are provided so as to be raised and lowered. The lifting frame 2 is provided with a rotating frame 8 rotatably supported, and a casing is inserted into a tapered hole formed in the rotating frame 8.

  Then, the chuck cylinder 6 is driven to insert a wedge member (not shown) between the casing and the tapered hole, and the rotating frame 8 and the casing are fastened, and the rotating frame 8 is fixed by the motor 9 disposed on the elevating frame 2. At the same time, the elevating cylinder 4 is lowered to rotationally press-fit the casing. The base frame 3 is provided with a jack 5 for adjusting the level of the entire tubing device 1. The jack 5 is also used when attaching and detaching the crawler side frame 30.

  Further, the base frame 3 is provided with a main body side bracket 10 for attaching the crawler side frame 30. The main body side brackets 10 are provided two each on the left and right sides of the base frame 3. In addition, the crawler side bracket 31 is provided in the crawler side frame 30 corresponding to the main body side bracket 10. The crawler side frame 30 is attached to the base frame 3 using the brackets 10 and 31. Details of each of the brackets 10 and 31 will be described later.

  Further, hydraulic pressure is supplied to the tubing device 1 from a hydraulic unit 40 for hydraulically driving each part via a hydraulic hose. Further, a weight mount 50 for loading the counterweight 51 is attached to the tubing device 1. The weight mount 50 is detachable, and is mounted above the crawler side frame 30.

  Here, the brackets 10 and 31 will be described with reference to FIGS. 4 to 7. FIG. 4 is a front view of the main body side bracket. FIG. 5 is a view showing the shape of the guide pin. 6 is a cross-sectional view taken along the line A-A of FIG. FIG. 7 is a front view of the crawler side bracket.

  As shown in FIG. 4, the upper pin hole 12 is formed in the upper part of the main body side bracket 10, and the lower pin hole 14 is formed in the lower part. Further, the main body side bracket 10 is provided with a guide pin 20. The upper pin hole 12, the lower pin hole 14 and the guide pin 20 are arranged in a straight line in the vertical direction. Thereby, the width direction dimension of the main body side bracket 10 becomes small, and the width dimension of the tubing device 1 in the state which has not attached the crawler side frame 30 can be made small. As a result, the width dimension of the tubing device 1 can be suppressed within the limitation of the transport width.

  The guide pin 20 is rotatably provided on the main body side bracket 10. The guide pin 20 has a pin outer peripheral surface 22 formed by the outer periphery of the guide pin 20 and an engaging portion 20a engaged with a guide hook 36 described later, as shown in FIGS. Center C2 is eccentrically located from center C1 and has a diameter D2 different from diameter D1 of guide pin 20 and is formed by an eccentric outer peripheral surface 24 formed by a circumference partially overlapping the pin outer periphery of guide pin 20 . The eccentric outer peripheral surface 24 acts as a cam mechanism.

  Further, at the end of the guide pin 20, a polygonal portion 26 for mounting a tool for rotating the guide pin 20 is formed. In the present embodiment, the polygonal portion 26 has a hexagonal shape. Thereby, the guide pin 20 can be easily rotated using a general-purpose tool (hexagonal wrench or the like).

  And in this embodiment, the diameter D2 of the eccentric outer peripheral surface 24 is smaller than the diameter D1 of the guide pin 20 (pin outer peripheral surface 22) (D1> D2), and the eccentric outer peripheral surface 24 is the engaging portion 20a. It has a shape which is more concave than the pin outer peripheral surface 22. Therefore, the position where the guide hooks 36 are engaged is visually clear, and the guide hooks 36 can be reliably engaged with the defined positions (recessed portions) of the guide pins 20 in a short time. This improves the mounting workability.

  On the other hand, in the crawler side bracket 31, as shown in FIG. 7, the upper pin hole 32 corresponding to (aligned with) the upper pin hole 12 of the main body side bracket 10 and the lower pin hole 14 of the main body side bracket 10 A corresponding (aligned) lower pin hole 34 is formed. Further, the crawler side bracket 31 is formed with a guide hook 36 engaged with the guide pin 20. Further, the crawler side bracket 31 is provided with a mount mounting pin hole 38. The mount mounting pin hole 38 is for mounting and fixing the weight mount 50.

Subsequently, a procedure for attaching the crawler side frame 30 to the above-described tubing device 1 (device main body) will be described with reference to FIGS. 8 to 14.
First, as shown in FIG. 8, the crawler side frame 30 is lifted using a wire rope W1 by a crane (lifting step). In addition, attachment to the crawler side frame 30 of the wire rope W1 is performed using the crawler hanging tool 60 for exclusive use. At this time, the jack 5 of the tubing device 1 is in an extended state.

  Next, as shown in FIG. 9, the lifted crawler side frame 30 (traveling device) is moved to the vicinity of the tubing device 1 by operating the crane. Then, as shown in FIG. 10, the guide hooks 36 of the crawler side bracket 31 are engaged with (hooked on) the guide pins 20 of the main body side bracket 10. At this time, in the guide pin 20, the eccentric outer peripheral surface 24 is located at the upper side, and the guide hook 36 is engaged with the recessed portion of the guide pin 20 (engagement process).

  By the engagement process, the crawler side frame 30 lifted by the crane is supported by the guide pins 20 and the guide hooks 36. Therefore, since the crawler side frame 30 lifted by the crane does not move carelessly, the safety of subsequent work can be secured.

  Further, the position of the upper pin hole 12 formed in the main body side bracket 10 substantially matches the position of the upper pin hole 32 of the crawler side bracket 31 by the engagement process. Similarly, the position of the lower pin hole 14 formed in the main body side bracket 10 and the position of the lower pin hole 34 of the crawler side bracket 31 substantially coincide with each other. At this stage, as shown in FIG. 11, the centers of the upper pin holes 12 and 32 (and the lower pin holes 14 and 34) do not completely coincide with each other (slightly, the pin holes 32 of the crawler side bracket 31 34) shifted downward). Since the crawler side frame 30 is lifted by the crane while the guide hook 36 is engaged with the guide pin 20, no large load acts on the guide pin 20.

  Next, the center of the upper pin hole 12 formed in the main body side bracket 10 and the center of the upper pin hole 32 of the crawler side bracket 31 are precisely aligned in order to fix the pin on the upper side of each bracket 10, 31 Let Specifically, a hexagonal wrench is attached to the polygonal portion 26 of the guide pin 20, and the guide pin 20 is rotated as shown in FIGS. Thereby, in the guide pin 20, the location of the eccentric outer peripheral surface 24 in contact with the guide hook 36 changes. That is, since the contact point between the guide pin 20 and the guide hook 36 gradually moves away from the center of rotation of the guide pin 20 by the cam mechanism as the guide pin 20 rotates, the crawler side bracket 31 moves upward. Therefore, by rotating the guide pin 20, the height position of the crawler bracket 31 can be adjusted. The adjustment of the position of the crawler bracket 31 in the left-right direction can be performed by adjusting the tension of the wire rope W1. As a result, as shown in FIG. 13, the center of the upper pin hole 32 of the crawler side bracket 31 and the center of the upper pin hole 12 of the main body side bracket 10 can be precisely aligned (alignment process).

  Then, the fixing pin P1 is driven into the aligned upper pin holes 12 and 32 (fixing step). Thus, the brackets 10 and 31 are fixed at the upper side (one point). The hexagonal wrench may be removed after driving in the fixing pin P1. Thereafter, the crane is operated to adjust the tension of the wire rope W1, and the crawler side bracket 31 is slightly rotated (moved) about the fixing pin P1 (upper pin hole 32), as shown in FIG. Thus, the center of the lower pin hole 34 can be precisely aligned with the center of the lower pin hole 14 of the main body side bracket 10 (alignment step). Then, the fixing pin P2 is driven into the aligned lower pin holes 14 and 34 (fixing step). Thus, the crawler side frame 30 is attached and pinned to the tubing device 1.

  Finally, a hexagonal wrench is again attached to the polygonal portion 26 of the guide pin 20 and the guide pin 20 is rotated to separate the guide pin 20 from the guide hook 36 (a separation step). As a result, after the crawler side frame 30 is attached to the tubing device 1, no load acts on the guide pins 20. And, even during the attachment work of the crawler side frame 30, a large load does not act on the guide pin 20. From these things, it is not necessary to make the size (diameter) of the guide pin 20 with which the guide hook 36 engages larger than a fixing pin, and a large space is unnecessary to provide the guide pin 20. That is, even the attachment utilizing the guide hooks 36 does not require a large space in structure as in the prior art.

  When the attachment of the crawler side frame 30 to the tubing device 1 is completed, the weight rack 50 is attached above the crawler side frame 30. At this time, the jack 5 of the tubing device 1 is in a contracted state. In the attachment of the weight rack 50, as shown in FIG. 15, the weight rack 50 lifted using the wire rope W2 is moved to the upper side of the crawler side frame 30. Then, first, the mounting portion 52 of the weight mount 50 is disposed on the mount mounting surface 39 provided on the crawler side frame 30. Next, the tension of the wire rope W2 is adjusted, and the mount mounting pin holes 38 of the crawler side bracket 31 and the pin holes 53 of the weight mount 50 are made to coincide with each other. Then, as shown in FIG. 16, the fixing pin P3 is driven into the matched pin holes 38 and 53. Thus, the weight rack 50 is fixed above the crawler side frame 30. Thereafter, the counterweight 51 is loaded in the weight mount frame 50.

  As described above in detail, according to the tubing device 1 and the attachment method of the crawler side frame 30 according to the present embodiment, the crawler side frame 30 lifted by a crane is first moved to form the crawler side bracket 31 The guide hooks 36 are engaged with the guide pins 20 provided on the main body side bracket 10. As a result, approximate alignment of the upper pin holes 12 and 32 and the lower pin holes 14 and 34 formed in the brackets 10 and 31 is performed. Next, with the guide hook 36 engaged with the guide pin 20, the position of the upper pin hole 32 of the crawler side bracket 31 is moved upward by rotating the guide pin 20, and the height position is adjusted. . Thus, the centers of the upper pin holes formed in the brackets 10 and 31 can be made to coincide with each other with high accuracy. Then, the fixing pin P1 is driven into the upper pin holes 12, 32 whose centers coincide with each other. Thereafter, the fixing pin P2 is also driven into the lower pin holes 14 and 34, and the crawler side frame 30 is attached and fixed to the tubing device body.

  As described above, according to the method of attaching the tubing device 1 and the crawler side frame 30 according to the present embodiment, the fixing pin is first formed on each of the brackets 10 and 31 by a very simple operation of rotating the guide pin 20. The centers of the upper pin holes to be driven can be made to coincide with each other, and the fixing pin P1 can be driven in efficiently. Then, when one point is fixed, the driving of the fixing pin P2 into the lower pin holes 14 and 34 can be easily performed. Therefore, the attachment of the crawler side frame 30 to the tubing device 1 can be efficiently performed by pin fixing.

  And, since the crawler side frame 30 is fixed at two places to the main body of the tubing device, a large load does not act on the guide pin 20, so the size (diameter) of the guide pin 20 needs to be increased. Absent. Therefore, the crawler side frame 30 can be efficiently attached to the tubing device 1 by pin fixing without increasing the size of the attachment structure.

  In addition, since the guide hook 36 is engaged with the guide pin 20 during the installation operation of the crawler side frame 30, the crawler side frame 30 lifted by the crane is supported by the guide pin 20 and the guide hook 36. Therefore, the safety during work is improved.

  The embodiment described above is merely an example, and does not limit the present invention in any way, and it goes without saying that various improvements and modifications can be made without departing from the scope of the invention. Although the above-mentioned embodiment illustrated the case where the present invention was applied to a tubing device as an example of a construction machine, the present invention is also applied to a construction machine (for example, an excavator, an earth drill, etc.) be able to.

  In the above embodiment, the guide pin 20 is provided on the main body side bracket 10 and the guide hook 36 is formed on the crawler side bracket 31. However, the guide pin 20 and the guide hook 36 are reversed. It can also be provided. That is, as shown in FIG. 17, the guide pin 20 can be provided on the crawler side bracket 31 and the guide hook 36 can be formed on the main body side bracket 10.
